R1150gs start up issues

[Leftybeard]

Hi guys, need help
I own an r1150gs 2002. Had a flat battery, I live on a hill so bumped it no worries.
Happened again ,tried to bump start, nothing, it was cold mind. Tried to jump it from a car, still nothing, just turning over without firing.
So, tank off battery out(cheap shite) and replaced with fully charged yuasa 51913. Tank back on, all connected up and...... nothing, just a click from starter. Not even any ignition noise, you know, when you first turn key, before ignition button.
Some advice would be greatly appreciated

Revisit all the work you did whilst changing battery. Particularly the fuel tank electrical connector. For fuel pump priming.

All the indications are that the battery does not have enough capacity to provide the current to turn the starter motor, or the starter motor is shorting out. All the ignition lights going out when you press the start button points to a high current short.

Check battery connections clean and tight
Check battery voltage fully charged.
Faulty Battery

Does the bike have an alarm/immobiliser fitted?

go to starter motor next maybe jammed happen to me thought it was a battery.

I'll get home later this afternoon and start again, no immobiliser unless the small red led on dash is indicator for one, don't know.
Battery was at 13v when I installed and now at 12.

1) Single Click from starter ??

2) Click click click, repeatedly??

Yes to Q1 If the instrument panel lights + RID backlighting Dim then it is likely a starter where the magnet has fallen off and jammed the starter You can replace the rear section with a new starter or a replacement case with Magnets is a quick fix I think I still have 2 of these in stock

Yes to Q2 then it is more likely to be a connection fault !

Think of the status of the bike before you changed the battery.

If the fuel pump primed when ignition turned on, and the starter motor turned the engine over, then all the indications are you’ve induced a fault or faults by changing the battery.

It could be you bought a faulty battery. The way of checking is to put a volt meter across the battery terminals and check the voltage during cranking (When you press the start button). On a good battery the voltage should stay high dropping by 1 or 2 volts. Any more than that and you’re looking at either a faulty battery or a faulty starter motor.

You said the bike turned over with the original battery, so refit it and see if the bike still turns over. If it does, you can rule out starter motor. It would firmly point to you fitting a faulty battery.

The red LED on the dash points to some form of Alarm/immobiliser. It’s certainly not standard fit so an after market device fitted by a previous owner. These can be a nightmare to fault find any problem with a bike where there could be a faulty alarm/immobiliser, so be warned.

So, I retraced my steps, tank off, battery off, still reading 12.5v, charged it again, back on, made sure all connections were tight and sound, and nothing.
No sound from fuel pump, then start button and one click, I held it down and it went to multiple clicks for a while , then back to just one.
I think I have two issues, starter is jammed and after market immobiliser.
I may have to except defeat and give it to the experts to solve

Check your fuses,
No 5 motronic and No 6 Fuel pump. If both good swop the the fuel pump relay with the horn relay and see if you can get the fuel pump to prime.

When you jump started it from a car, was the car engine running?

I'll try that, yes car was running

For reference, it’s not a good idea to try to jump start a motorcycle from a car with the car engine running. Motorcycle charging systems are not like cars.
Always jump start with the donor vehicle static.

I think I have two issues, starter is jammed and after market immobiliser.

My thoughts too.

 

[ynotbiker]

My money is on the starter £60 eBay

 

[ynotbiker]

well £64 it’s a cargo not a bad make.

So, I tried that, fuses all fine, swapped the relays and still same, horn working, so not the relay. Think it's to do with the immobiliser. Spoke to previous owner and he had no problem when he had battery out, so I'm stumped.

 

[Leftybeard]

Yeah, could be part of the problem

 

[Paul G (BHT)]

My money is on the starter....

But a dodgy starter wouldn't stop the fuel pump priming when turning the ignition key on

 

[Keith Chapman]

Sounds like there are two problems. Jammed starter and no feed to the fuel pump. Startermotors had a habit of dropping magnets that then jammed. What happens to the instruments and warning lights when the ignition is turned on? Could your issue be a fault in the ignition switch wiring or hall sensor.

Have a look at the video in post #2

let me get this right.

Before you changed the battery, the engine would not turn over but you were able to bump start it. Presumably you also had the usual ignition on sound of the fuel pump priming.

You tried jump started it from a Car with the car engine running, and it would turn over, (starter working) but not start.
Can you remember if you had the usual ignition on sounds of fuel pump priming at that point.

You then changed the battery with a new fully charged lead acid battery and you get no fuel pump priming and when you press the start button, all you get is a clunk from the starter solenoid and all your ignition lights go out.

My first thoughts would be, is the battery good, is the acid electrolyte correct to allow the battery to deliver the current required of it.

Put a voltmeter across the battery and measure the voltage with ignition OFF and On, there should be little change.

What happens when you jump the motorcycle battery from the Car. (making sure the car engine is not running).
